pplication iiled January 28, 1907. Serial No. 354389- This invention relates to lmprovements in the manufacture of pins such as are usedv principaliy for ornamental wear and the primary object of the invention is to provide said pin with anY integral catch piece and joint-ears that are formed heavier or made thicker than the body of the pin to strengthen the same. lIn the construction of pins from high grade or expensive material, such as solid orold, silver, heavy rolled plate stock or the 2like, the body portion may be made very light or thin and still, owing to its cupped shape form, be sufficiently 'strong and durable for all practical purposes. 'When a cud pin is consi ructed of such thin stock it has heretofore boe-n found necessary to form the joint-ears and catch piece separately and of heavier stock and to'solder the same to the body, as when'they were-made all in one piece with the body portion, they were so thin and light that they were unsubstantial and not practical, being easily broken of and the pin Idestroyed.

When it was desired to make the ears and tongue ,integral with the body in a practical manner the stock of the body had to be much Vthicker than was necessary in order to get the ears of sufficient strength to stand the strains, thus unnecessarily increasing the cost of the pin.

My improved cuff Din is constructed to obi viate the above difficulties rendering it possible and practicable to form a pin body eX- tremely thin and l-ight and at the same time provide said body with joint-ears and catch suHicient strength and stiffness to easily withstand the strains required of them.

' My invention is fully set forth in this specification and more particularly pointed out in the appended claims.

In the accompanying drawings: Figure I 1s an enlarged view of a completed pm show- Ing the same constructed 1n my Improved manner and the pin tongue in position in the joint andcatch. Fig. Z-represents-a flat 'it in position.

piece of stock which has been rolled, stamped i or otherwise swaged to the desired thickness showing the joint-ears hand catch raised or thickened on the surface `of the platefthe outline vof the pin body being shown in dotted lines. Fig. 3-shows the pin blank cut from the sheet stock. Fig. 4'-is an enlarged section on line 4-4 of Fig. 2 illustrating the thickened or reinforced ears, the center portion between the ears representing the thickness of the body of the pin. Fig. 5-is Va secat either end representing the thickened tongue and joint-ear, the balance of. the stock representing the comparative thickness of the body of the pin.

between and around the raised portionsof the ears within the body ofthe iin. Fig. 7 is ,a perspective view of the fuicrum plate bent into proper form to be applied .to the pin body. Fig. S-represents one of. the pins in section showing a reinforced catch or joint-ear also the fulcrum plate in position in the pin. Fig. Q-is an enlarged section on line 9-9 of Fig. 8 showing the thickened joint-ears, as compared.l to the thinl shell. Fig. 10-is a section similar to that of Fig. 9 showing the fulcrum plate as held in position between the ears by setting said ears inward to grip or bind said 'plate and hold Fig. ll-shows a pair of rolls with recesses in the face of one, for forming thickened portions on the stock as it is passed therethrough.

Y tion on line 5-5 of Fig-2 the raisedportions y Fig. G-shows /a' blank form of fulcrum plate adapted `to fit Referring to the drawings at 1v is the body portion of the pin which is constructed of sheet metal, said metal being rolled, s'waged or stamped to the desired thickness. In constructing this pin of solid gold or silver or of a heavy roll plate stock it is desirable, on account of the 'expense ofthe stock as well as the' ease with which the saine is worked, to form the body ofthe pin as thin as possible and the catch member 2 and ears 30 recessedatV 7--7 tol t'over the' raised por same time lthe stock for the body portion 1s bemgreduced Ito the required thickness,

if desired. One Way of forming these thick- Vpoints which are subsequently formed into joint-ears' andk catches. I do lnot confine myself, however', to the production of these raised portions by the rolling of the stock as y the Same result maybe obtained by stamping, vswaging or by any. .other means Without de# parting from the spirit and scope of my invention.

In forming these vears and the catch portion the stock is preferably raised or thickened on the inner side `at 4 4 of. thev body 1 lwhich thickened portion is carried Well doWn into'the body portion at 5-5 thereby providing a substantial reinforcement at the pointsvvhich are called upon 4to Withstand the most strain. By thickening the stock on the inner. face of the ears and catch,v the outside. surface of the same remains' smooth and regular, and even with the outer face of the 4body'portim..l A fulcrum plate fis `preferably stam ed out of sheet metal tions .4 vof the ears and between said ears when they are turned dovvn into-the position to receive the tongue. Any suitable bearing for .this fulcrum plate may be arrangedfbut I'have shown the ends SvS of the'plate- 'as ,bent over to restagainst the bottom. or' inner surface of the body ofthe As illustrate-din Fig. 10 the ears 3 3 may liecarried inward so'as to better grip, bind and retain the said fulcrum plate firmly in position. The pin tongue may be placed in position in the usual'Way andthepin is ready for'service.

From the foregoing it Will be readily perceived that I have produced a pin the body portion of which may be made of thin material, whereby the same may' be readily shaped, embossed, Aor otherwise Worked, thereby insuring a saving'` in the cost of manu- 'facture and at the same time presenting a neat and finished appearance. AIt Will be further observed that by thickening the metal to reinforce the joint ears and catch I avoid the expense and save the time incident to the soldering of separate joint ears and catches, or reinforcing pieces, and yet produce a durable and inex ensive pin.

Having thus describedlmy invention, What yI claim as new and desire to secure by Letters Patent, is:

l'. An article of manufacture comprising a pin formed of sheet metal shaped to the-desired form and provided With integral catch and joint ears which are of greater thickness than the body portion of said pin.

2. An article of manufacture comprising ae..

sired form and provided with integral joint ears which are of greater thickness than the body portion of said pin.

4. An article of manufactureV comprisin 'av pin formed of sheet metal shaped to the esired form and provided With integral catch and joint ears, said catch member and ears being thicker than the body of the pin, the thickened said body;

5. An article of manufacture comprising a` pin formed of sheet metal shaped to .the desired form and provided With integral catch and joint ears which are of greater thickness than the body of said pin, and a fulcrurn member notched to engage the thickened portions of said joint ears, the latter being bent to retain said fulcrum member in posi tion. i

6. An article of manufacture comprising a pin formed of sheet metal shaped to .thedesired form and provided `with integral catch and joint ears which are of greater thicknes: than the body of said pin, and a fulcrum member having projections which' straddle the thickened portions of said joint ears, said projections being bent over to rest against the body portion of the pin, said ears being bent inward to retain said fulcrum member in position.

In testimony whereof I affix my signature in presence of two Witnesses.
